摘要/Abstract

摘要： Acrylic acid was graft-copolymerized onto Rhi. oryzae’s cell wall structural polysacchaxide
directly and efficiently in aqueous solution with ceric ammonium nitrate as initiator. The
maximal grafting percentage of 135.5％ was obtained under the condition of [Ce4+]＝5mmol.L
-1, [AA]=1mol.L-1, T＝60°C and t＝3h. Graft copolymerization was suggested to proceed
through free radical reaction mechanism. Grafting occurred primarily on chitosan. Acrylic
acid was also attempted to be grafted onto Asp. niger cell wall structural polysaccharide,
and only 44.2％ of grafting percentage was resulted.
